Could recalling happy memories help heal PTSD?
NCT ID NCT05523453
First seen Jun 27, 2026 · Last updated Sep 01, 2026 · Updated 2 times
Summary
This study tested a new therapy called Processing of Positive Memories Technique (PPMT) for people with PTSD. Unlike standard treatments that focus on trauma, PPMT helps patients recall and describe positive memories. 70 adults with PTSD were randomly assigned to either PPMT or supportive counseling. Researchers measured changes in PTSD symptoms and stress hormones to see if this approach could offer relief.
